802.11g wlan phy model

It is a modified version 802.11a

Modulator has been initialized as

% number of bits per symbol

switch modulation

case 'BPSK', Nb1 = 1;

case 'QPSK', Nb1 = 2;

case '16-QAM', Nb1 = 4;

case '64-QAM', Nb1 = 6;

case 'DQPSK', Nb1 = 8;

case 'OQPSK', Nb1 = 16;

end

modOrder = 2.^Nb1;

Nb = numSymbols * Nb1; % tx bits per block

codeRate = str2num(strvcat(code)).';

bitsPerBlock = Nb .* codeRate;

% interleaver

interleaverRows = 16;

if rem(Nb, interleaverRows)

error('Number of transmitted bits per block must be multiple of 16.')

end

interleaverCols = Nb / interleaverRows;

interleaverElements = [...

2*floor( [0:Nb-1]/2 ) + ...

mod( ([0:Nb-1] + Nb - floor( interleaverRows*[0:Nb-1]/Nb ) ), 2 ) ...

+ 1]';

The models looks like 802.11a but parameters used here are for 802.11g
